IMPROVEMENT IN GAGE-PINS FOR PRINTlN G-PRESSES.

Specification forming part of Letters Patent No. 179,539, dated July 1,1876; application filed May 13, 1876.

To all whom it may concern:

Be it known that I, WELLINGTON H. EAST- MAN, of Auburn, in the county ofAndroscoggin and State of Maine, have invented a new and valuableImprovement in Gage-Pins for Printing-Presses; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure l of the drawings is a representatiouof a perspective, showing mygage applied to a platen; and Fig. 2 is a bottom View of the same. Fig.3 is a side view, and Fig. 4 is a cross-section.

.The nature of my invention consists in the construction and arrangementof a n adjustable feed-gage for printing-presses, as will be hereinaftermore fully set forth.

In the annexedvdrawing, A represents a fiat metal strip or bar ofsuitable dimensions, provided at one end with a head, B. This metalstrip is placed in guides a a, formed along the edges, either on top orbottom, of a similar flat metal strip, A, which is, at the opposite end,provided with a head, B. The two parts thus placed one within the other,may be extended and contracted as required, and an elastic band, (I, ispassed around them longitudinally, as shown. The heads B B are provi'dedwith downwardly-projecting ears or lugs b, between which the elasticband 01 is passed. To these cars or lugs 12 are fastened points x 41;.The points at opposite ends of the gage extend toward each other andacross the platen, or at right angles to the work, said points beinginserted in the platen sheets. When the points are thus inserted, theelastic band holds the gage to its place.

By means of the slide the gage may be extended crosswise of the platen,thereby making it adjustable to the width of the work.

By this construction of the gage the holes in the tympau-sheet are madevery small, so that the gage may be slightly moved without the sheetstearing out. This end is further aided by the pins being at right anglesto the work.

Only one gage need to be used, unless the sheet is of considerablewidth.

What I claim as new, and desire to secure by Letters Patent, is v 1. Agage-pin or feed-gage for printingpresses, provided with two sets ofpoints, extending inward toward each other, as and for the purpose setforth.

2. An adjustable sliding gage-pin or feedgage for printing-presses,provided with inwardly-projecting points, and an elastic band passinglongitudinally around the same, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WELLINGTON HARRIS EASTMAN.
